Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 43,542,121, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 43,542,121 | |
| -1 | -43,542,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,542,121.
Example:
1 x 43,542,121 = 43,542,121
and
-1 x -43,542,121 = 43,542,121
Notice both answers equal 43,542,121
With that explanation out of the way, let's continue. Next, we take the number 43,542,121 and divide it by 2:
43,542,121 ÷ 2 = 21,771,060.5
If the quotient is a whole number, then 2 and 21,771,060.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,542,121 | |
| -1 | -43,542,121 |
Now, we try dividing 43,542,121 by 3:
43,542,121 ÷ 3 = 14,514,040.3333
If the quotient is a whole number, then 3 and 14,514,040.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,542,121 | |
| -1 | -43,542,121 |
Let's try dividing by 4:
43,542,121 ÷ 4 = 10,885,530.25
If the quotient is a whole number, then 4 and 10,885,530.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,542,121 | |
| -1 | 43,542,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 149 | 383 | 763 | 1,043 | 2,681 | 16,241 | 41,747 | 57,067 | 113,687 | 292,229 | 399,469 | 6,220,303 | 43,542,121 |
| -1 | -7 | -109 | -149 | -383 | -763 | -1,043 | -2,681 | -16,241 | -41,747 | -57,067 | -113,687 | -292,229 | -399,469 | -6,220,303 | -43,542,121 |
